The manufacturing method of the polyester composite board structure comprises the steps of extruding a polyester layer into a board by using a multi-layer extrusion device, and thermally bonding a polyester film by using a wheel in the extrusion process.
In one embodiment of the present invention, the melting temperature of the multilayer extrusion device is 250 ℃ to 290 ℃.
In one embodiment of the present invention, the polyester layer comprises a recycled polyester resin layer (which may be PET or a generally thermoplastic polyester, such as PC, PBT, PBAT, etc., having a thickness of 0.3mm to 6.0mm and providing mainly support for the composite board), a functional polyester layer (which may be PET or a generally thermoplastic polyester, such as PC, PBT, PBAT, etc., having a thickness of 0.12mm to 4.0mm and providing mainly functional properties of the composite board, such as color, pattern, etc.), or a protective polyester layer (which may be PET or a generally thermoplastic polyester, such as PC, PBT, PBAT, etc., having a thickness of 0.06mm to 1.0mm and providing mainly protective functions of the composite board, such as scratch resistance, solvent resistance, etc.).
In one embodiment of the present invention, the lamination temperature of the heat-laminated polyester film using the wheel is 80 to 180 ℃.

In one embodiment of the invention, the thickness is 0.6mm to 10mm.
In one embodiment of the present invention, the polyester film comprises 1 to 5 polyester layers and 1 to 2 polyester films (which may be a transparent PET film, a PET film with printing process, or a thermoplastic polyester film, such as PC, PBT, PBAT film, and the thickness is from 12um to 250um, and the thickness mainly provides additional functions of the composite board, such as decorative patterns, antibacterial, mildew-proof, wear-resistant, scratch-resistant performances, etc.).
In one embodiment of the present invention, the polyester layer comprises a recycled polyester resin layer (which may be PET or a generally thermoplastic polyester, such as PC, PBT, PBAT, etc., having a thickness of 0.3mm to 6.0mm and providing mainly support for the composite board), a functional polyester layer (which may be PET or a generally thermoplastic polyester, such as PC, PBT, PBAT, etc., having a thickness of 0.12mm to 4.0mm and providing mainly functional properties of the composite board, such as color, pattern, etc.), or a protective polyester layer (which may be PET or a generally thermoplastic polyester, such as PC, PBT, PBAT, etc., having a thickness of 0.06mm to 1.0mm and providing mainly protective functions of the composite board, such as scratch resistance, solvent resistance, etc.)

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail. However, these embodiments are illustrative, and the present disclosure is not limited thereto.
In this document, a range from "one value to another value" is a shorthand way of referring individually to all the values in the range, which are avoided in the specification. Thus, recitation of a particular numerical range includes any numerical value within that range, as well as the smaller numerical range bounded by any numerical value within that range, as if the any numerical value and the smaller numerical range were written in the specification.
The invention provides a polyester composite board structure and a manufacturing method thereof.
In this embodiment, the melting temperature of the multi-layer extrusion apparatus is, for example, 250 ℃ to 290 ℃, and two or three multi-layer extrusion apparatuses can be used to manufacture the upper layer, the middle layer or the bottom layer, respectively. The polyester layer may include recycled polyester resin layer (which may be PET or general thermoplastic type polyester, such as PC, PBT, PBAT, etc. and has a thickness of 0.3mm to 6.0mm, and mainly provides support for the composite board), functional polyester layer (which may be PET or general thermoplastic type polyester, such as PC, PBT, PBAT, etc. and has a thickness of 0.12mm to 4.0mm, and mainly provides functional properties of the composite board, such as color, pattern, etc.), or protective polyester layer (which may be PET or general thermoplastic type polyester, such as PC, PBT, PBAT, etc. and has a thickness of 0.06mm to 1.0mm, and mainly provides protective functions of the composite board, such as scratch resistance, solvent resistance, etc.). The lamination temperature of the polyester film is 80 ℃ to 180 ℃ by using a wheel, and the wheel can comprise three rollers, for example, but the invention is not limited thereto. The polyester composite board structure manufactured by the manufacturing method of the invention has the thickness of 0.6mm to 10mm, for example, and can comprise 1 to 5 polyester layers and 1 to 2 polyester films.
In summary, the present invention provides a polyester composite board structure and a manufacturing method thereof, wherein a composite board structure is made of a single material, and the polyester film and the composite board are closely formed by the temperature of the wheel of the device and the thermoplastic property of polyester on the premise of not coating glue or heating and pressing, so that the polyester composite board structure has the performances of decoration pattern, antibiosis, mildew resistance, wear resistance, scratch resistance, etc., thereby meeting the requirements of environmental protection, energy conservation and carbon reduction. In addition, the recycled polyester resin layer can be used for extrusion into a plate, which accords with the trend of low-carbon green products.
